Another Round Of Terror Attacks In Russia

MOSCOW — Two explosions killed at least 12 people in the volatile North Caucasus region on Wednesday in what appeared to be attacks targeting the police, investigators from the Russian prosecutor’s office said.

One of the explosions was caused by a suicide bomber wearing a police uniform, officials said.

The bombings, which also injured at least two dozen people, occurred in Dagestan, a region of southern Russia that borders Chechnya, where attacks against the police occur almost daily.

The attacks came two days after two female suicide bombers set off explosions in the Moscow subway during the morning rush hour, killing 39 people, and they seemed to offer a further challenge to the Russian authorities.

Law enforcement agencies throughout the country have been on alert since the Moscow bombings, and Prime Minister Vladimir V. Putin has ordered the security forces to drag those responsible “out of the bottom of the sewer and into the light of God.”
